STORM-SEWER INLET.

Application filed May 27,

Our invention relates to improvements in storm sewer inlets, and itV consists in the combinations, constructions, and `arrangements herein described and claimed.

An object of our invention is to provide a storm sewer inlet Vin which the grating 1s so `curvedL vas to cause trash to be washed therefrom, which. would otherwise remain on the 'grating and clog it up if it were flat.

' greater clearance for the opening at the edge of the grating into the sewer, and without creating a sudden drop from the road surface or gutter onto the grating.

A further object of the inventionis to provide a device which is built in sections and in which the end members serve for sections of greater or less length, thus obviating the necessity of duplicating parts for various sized devices. Y

@ther objects and advantages will appear in the following specification, and the'novel features of the invention will be particularly pointed out in the appended claims.

Our invention is illustrated in the accompanying drawings, forming part of this ap-V plication, in which Y Figure 1 is a perspective view of the device, f

Figure 2 is a perspective view of a portion of the device as set in a curved curbing.

`Figure 3 is an enlarged transverse section through a. Vstorm sewer showing the storm inlet in position, and

Figure 4 is a plan View of the frame with the grating removed.

In carrying out our invention, we make use of end members such as those shown in Figure 1'.` It will be seenthat these end membody portion 1 having an integral upstanding portion 2 at one end thereof and an integral flange portion 3 extending substantially at right angles to the body portion. Surmounting the upstanding portions 2 is a cap'portion 4 having a downwardly extending flange 5y arranged to abut the outer edge of the upstand- 1927. serial No. 194,720.

ging portion 2 and having a smaller `flange Gy arranged'to enter a recess 7 in each of the end portions 2. This cap portion 4 haslugs 8 which lie close to the inner faces of the end portions 2 and which are secured to the end portions by. means of bolts 9 and nuts 1 On the side of the device next to the street is a plate 11 which has an integral liangef12 which abutsthe flange-l of cach of the end members. This plate has lugs 13 similar to the lugs 8, which lie close to the inner faces of the end members 1 and are secured thereto by means of bolts 14, see Figure 4. In order to further brace. the device, we provide a lbrace rod 15 having nuts 1G, between which and outer nutsv 17, the end members 2are clamped.

In order to support the grating 18, we provide supporting lugs 19 on the member 11 and similar lugs 20 on theend. members 1'. From the foregoing description of the various parts' of the device, the operation thereof may be readily understood. In Figure 3 we have Vshown how the storm inlet is disposed with i respect to the surface of the street. In this figure, the catch basin is shown at 21 and the storm sewer pipe 21', and it will be noted that the flange 12 of the member 11, as well as the flanges 3 of the end vmembers 1, are covered with the material of the roadway 22. The upper surface 23 of the roadway is flush with the upper surface of the member 11 and also of the grating 18.

The grating, it will be observed, is curved;

that is to say, downwardly from the street toward the opening 24' between the inner edge of the grating and the cap 4. This curvature tends to prevent the accumulation f of trash on the grating which might other wise tend to clog it and insures the sweeping away of the trashthrough the opening 24, which isunobstructed by cross-braces or other supports.

roadway is on a level at 11 and since the rcurved surface is parabolic, the dropbelow the road or gutter surfacel is reduced to aj minimum until the grating'approaches the immediate front face of curb. I

`When it is desired to increase the length of the inlet, itis only necessary to provide a longer grating cap corresponding to the member 11, the end portions vbeing available for shorter or longer lengths-,pas desired. y y

We claim:

Since the surface of the portion and portion f 1. A storm sewer inlet, comprising aV pair -e msf of spaced-apart end members, a plate connecting the ends of said end members, said members having integral upstanding extensions at the ends opposite said plate, a cap member for joining said extensions, and a grating supported by said end members and said connecting plate, said grating being curved downwardly from 'the side supported by said plate to the opposite side.

2. A. storm sewer inlet, comprising .a pair of end members, each of said end members having a laterally extending flange at its bottom and being, provided with an upstanding portion at one end, a plate for connecting said end members at one end thereof7 said plate having an outwardly extending flange at its bottom, a cap member having downwardly extending Hang-es arranged to tit over the upper surface of said extensions, means. for securing said cap member tov said extension, inwardly projecting lugs carried by said end members and said plate, and a grating carried by said lugs, one side of the grating being flush with the upper surface of said plate and the ends of the grating being 2 y ramasse flush with the upper surface of'said end members, the side of said grating opposite they supporting plate terminating in a-plane substantially coincident with the inner edges of said upstandin'g portions of the end members.

3. A storm sewer inlet,l comprising end members, each of said end members having a portion provided with a curved upper sur-- face and an integral upstanding portion having a flattop, a plate connecting the ends of the curved portion, a cap member surmounting the upper ends of said upstanding poi'- tions, means for securing said cap member to said upstanding portions, inwardly projecting lugsI carried by said end members and said plate, and a grating supported upon the lugs, one side of the grating being contiguous to and flush with the upper surface of the connecting plate and the ends of the grating beingk contiguous to and flush with the upper curved surfaces of the end members. 4
